Silquest A-Link 25 Silane 3-Isocyanatopropyltriethoxysilane Crompton-OSI Specialties Adhesion Promoters >> Organofunctional silane Crosslinking / Coupling / Curing Agents >> Silane Silicones (Si) PU - Prepolymers SEALANT ADHESIVE Silquest® A-Link™ 25 Silane 3-isocyanatopropyltriethoxysilane OSi Specialties Product Description: Silquest® A-Link™ 25 silane is a unique isocyanatosilane. The isocyanate functionality exhibits the typical reactivity of an alkyl isocyanate and will react with most active hydrogen containing compounds. The silane portion of these products can then crosslink with each other or be used to adhere to a variety of substrates. Silquest A-Link 25 silane provides slower hydrolysis for applications requiring greater open time or enhanced shelf stability. It provides superior wet adhesion to glass, metal and other inorganic substrates. The bond offered by Silquest A-Link 25 silane offers excellent thermal, chemical and UV stable performance. Provides slower hydrolysis for applications requiring greater open time or enhanced shelf stability. Unique isocyanatosilane. Used as crosslinker and adhesion promoter in adhesives and sealants. Provides adhesion to a variety of substrates, slow hydrolysis for applications requiring greater open time or enhanced shelf stability, superior wet adhesion to glass, metal and other inorganic substrates. Offers very good thermal, chemical and UV stability.
